The prism includes an uneven surface portion provided on at least one of the incident, reflecting or emitting surfaces and located outside a light transmission area through which effective light of an associated optical system, in which the prism is to be incorporated, can be transmitted. The disclosure is also directed to a real image type view finder having such a prism.
